It is important to purify proanthocyanidins, particularly for determining their conversion yield. It is also advantageous to do so to eliminate extraneous material that might otherwise react with the proanthocyanidins. A combination of liquid-liquid extraction and adsorption chromatography is effective in removing impurities. The use of chloroform in liquid-liquid extraction is very effective in removing fat-soluble compounds such as carotenoids, chlorophyll, oils, and waxes. These compounds would be expected in leafy plant tissues (carotenoids and chlorophyll) as well as seeds and fruits (oils and waxes). Ethyl acetate is effective in the selective removal of flavan-3-ol monomers, which are also typically present with proanthocyanidins. 

The members of this family are mostly tropical with a few temperate representatives. Several economic products come from the family the latex is used in chewing gum edible fruits, oils, guttapercha, and timber are also produced. A proteinaceous sweetener several times sweeter than sugar is also known from the family. 

In special cases genuine oils are adulterated with secondary products from the treatment of certain oils, as, for instance, the terpenes of the lemon for adulterating acid fruit oils (q.v.), or oils of high value are treated with others of similar odour but of much lower price (geranium oil being added to rose oil or citronella oil to melissa oil). 

Several volatile C.- norisoprenoids have previously been identified in steam-distilled quince fruit oil, in which they are regarded to contribute to the overall flavor impression. These include isomeric theaspiranes, various bicydononane derivatives, 3,4-didehydro- 3-ionol, and isomeric megastigmatrienones and theaspirones (4,5). This report concerns the identification of additional norisoprenoids and their natural precursors in quince fruit. 

Another C., norisoprenoid aglycone in quince fruit, 7,8-dihydrovomi-foliol (22) (cf. Figure 6), can be considered to be the precursor of theaspirones, which were previously found in steam-distilled quince fruit oil (4). As outlined in Figure 8, a synthetic sequence from ot-ionone via dehydrovomifoliol (25) and vomifoliol (21) leads to 7,8-dihydrovomifoliol (22), from which the isomeric theaspirones 26A/26B are formed after thermal treatment (18).

The chief components of the celery leaf oil were limonene, myrcene and cis-ocimene (Bubarova, 1973 Fehr, 1974). The sesquiterpene content of the leaf oil (< 5%) was relatively low compared with that of the fruit oil. The essential oil of leaves contained a higher amount of limonene compared with the roots and a very small amount of carvone (Sipailiene et al., 2005). Studies conducted on the leaf essential oil showed that the matured dry leaf contained essential oil having a composition similar to that of seed oil (Thappa et al., 2003). High... 

The flavour volatile constituents of the seed cotyledons, fruits and leaves of M. koenigii L. were analysed by GC-MS and compared with curry leaf flavour constituents (Walde et al., 2005). These consist of monoterpene hydrocarbons, oxygenated monoterpenes and sesquiterpenes. The major constituents of curry leaf are monoterpenes (70%), seed cotyledons (86%) constituting a-pinene (52%) and c/s-P-ocimene (34%) raw fruit oil containing monoterpenes (80%) and oxygenated monoterpenes (4.8%) and fruit pulp oil containing monoterpenes (61%).

Steam distillation is used when normal distillation is not an option, due to thermal sensitivities. By adding water or steam, the boiling points of compounds can be depressed, allowing them to evaporate at lower temperatures. After distillation the vapours are condensed and typically yield two phases water and organics. These can then be easily separated on the basis of their different densities. On a simple level, this can be seen every day in fresh black coffee, where small amounts of organic, water-immiscible oils float on the surface. Steam distillation is employed on an industrial scale in the manufacture of essential oils (e.g. lavender, eucalyptus and fruit oils) that are used in the food and flavour industries. In this area, the use of water is highly desirable as a natural solvent. Steam distillation is also used in petroleum refineries and petrochemical plants, where it is commonly referred to as steam stripping . 

The woody pit inside the mesocarp holds a seed whose oil is more unsaturted than the mesocarp (pulp) oil because of a higher content of linoleic acid. The ratio of fruit oil to seed oil is 50 1. 

Mechanical extraction of the palm oil from the digested pahn fmit is a dehcate process. The screw press must squeeze as much oil as possible from the fruit without breaking the palm kernels. Pahn-kemel oil will mix with the pahn fruit oil if the kernels are crushed. International trading rules allow a maximum of 5% pahn-kernel oil in pahn oil.

Composition ISO lists 65-78% linalool, a-pinene (3-7%), y-terpinene (2-7%), camphor (4-6%), limonene (2-5%), geranyl acetate (1-3.5%), geraniol (0.5-3%), a-terpi-neol (0.5-1.5%) and myrcene (0.5-1.5%) [75] as the main components of coriander fruit oil. Further constituents can be linalyl acetate, bomeol, citronellol, nerol, ter-pinene-4-ol, additionally monoterpene hydrocarbons and aliphatic aldehydes [76, 77], The latter are the main components of the weed (cilantro) oil and their amount is higher in unripe coriander fruits. E-2-tridecanal is held responsible for the bug-like odour of these unripe fruits ( bug dill ) [78], Lamparsky and Klimes have performed an exhaustive analysis which also led to the detection of interesting heterocyclic trace constituents [79],...
